Capitol Reef National Park is a national park of the United States in south-central Utah. The park is approximately 60 miles (100 km) long on its north–south axis and just 6 miles (10 km) wide on average. The park was established in 1971 to preserve 241,904 acres (377.98 sq mi; 97,895.08 ha; 978.95 km²) of desert landscape and is open all year, with May through September receiving the most visitors.

Partially in Wayne County, Utah, the area was originally named "Wayne Wonderland" in the 1920s by local boosters Ephraim P. Pectol and Joseph S. Hickman. Capitol Reef National Park was designated a national monument on August 2, 1937, by President Franklin D. Roosevelt to protect the area's colorful canyons, ridges, buttes, and monoliths; however, it was not until 1950 that the area officially opened to the public. Road access was improved in 1962 with the construction of State Route 24 through the Fremont River Canyon.

The majority of the nearly 100-mile-long (160-kilometer) up-thrust formation called the Waterpocket Fold—a rocky spine extending from Thousand Lake Mountain to Lake Powell—is preserved within the park. Capitol Reef is an especially rugged and spectacular segment of the Waterpocket Fold by the Fremont River. The park was named for its whitish Navajo Sandstone cliffs with dome formations—similar to the white domes often placed on capitol buildings—that run from the Fremont River to Pleasant Creek on the Waterpocket Fold. Locally, reef refers to any rocky barrier to land travel, just as ocean reefs are barriers to sea travel.
